So im going to sell my 13 MBP for a 15" new one. Im going to be doing primarily standard websurfing /movies/music etc plus photoshop and xcode (beginning to develop for iOS). Right now the screen size on the 13 is feeling cramped especially in xcode and photoshop so i want a 15. My question is regarding to get the low end 15 with the standard screen or upgrade to the high res screen. I would get the high res screen no questions asked if it was available in store but if i order it online im not sure how long it will take to get and i need to sell my computer before purchasing the new one so ill be without a computer for who knows how long. this is not good because im currently in college and need a computer. what do you guys think? just go with the standard screen?
